High temperature shift conversion (HTSC) is a water gas shift reaction using water to produce hydrogen and carbon dioxide in high temperature (370-400 degrees C). HTSC catalyst used in industry usually has Fe/Cr as a base component. In Indonesia, the demand of HTSC catalyst is still high although the national fertilizer production is decrease. This research is expected to produce a method of catalyst preparation that has a similar performance with the commercial and using domestic raw material.<p> <br /> <br /> <br /> <br /> <br /> The aim of this research is examining the preparation procedure of catalyst based on patent no. 4.482.645 (Jennings, 1984) in laboratory scale. The catalyst made by Co-precipitation method of Fe and Cr nitrate solution with Na2CO3 as precipitating agent. The specific surface area of catalyst was determined by BET method. The crystal structure was analyzed by XRD method. The catalyst activity was evaluated by means of fixed bed reactor with 12.5%-v CO inlet gas composition, 0.87 steam to gas ratio, and 2234 hour degree -1 VHSV.<p> <br /> <br /> <br /> <br /> <br /> The result shows that the preparation procedure of HTSC ITB catalyst is reproducible. Based on the preparation procedure, calcinations temperature has a great influence to the catalyst surface area. The calcinations temperature at 300 degrees C gave the highest catalyst surface area (198 m2/g), and it is comparable with the surface area claimed by Jennings (200 m2/g). The catalyst has also the highest activity by means of CO conversion resulted by the catalyst activity test (86%) which is larger than commercial catalyst conversion (81%).
